That does look like a good use of space, especially if you had nice minimalist shower panels. The window would have either frosted glaze or at least frosted film, so the bath near it would be nice for the light but not the view - it's a window that looks out onto the street anyway.
My concerns would be:
Poo particles near the toothbrush (overcome by keeping them in a cupboard I suppose, tidier anyway)
The current window is wooden-framed and while we'd ideally replace it, I'm not sure we can afford to - so having a shower right next to it might be better avoided
